Prioritize features that can be compared with the missing person's description and records, distinguishing a general biological profile from a distinctive match. The problem asks what to observe; it supplies no actual bones from which to invent an identification.
Begin by documenting recovery and association. Lay out and inventory the remains, confirm that they are human, and consider whether all the bones could belong to one individual. Note missing or duplicated elements and any damage from animals, burial or recovery. An apparent absence is informative only if the relevant part was actually recovered and examined. Keep the teeth and small fragments; they may contain the most useful identifying information.
Estimate age using several indicators. In the young, tooth development and eruption, growth and fusion of the epiphyses are useful. In adults, changes at the pubic symphysis, rib ends and teeth may help, but provide ranges rather than an exact birthday. Tooth wear depends on diet and habits, and cranial suture closure is variable. The human skeleton's developmental and pathological changes must be interpreted together rather than converted into an unjustifiably precise age.[ref]

For estimated sex, give particular attention to the adult pelvis: the greater sciatic notch, subpubic region and overall form are more informative than size alone. Features of the skull can assist, but robusticity is variable and overlapping. Immature remains often do not support the same degree of certainty. For stature, measure preserved long bones, especially the femur and tibia, or reconstruct skeletal length if sufficiently complete. State the method and uncertainty: bone length is not living height, and neither sex nor stature should be inferred solely from a large or small skull.[ref]

The most discriminating observations may be particular departures from the usual anatomy: an old healed fracture with shortening or angulation, an amputation, congenital deformity, fused anatomical joints, unusual disease changes, or a distinctive pattern of missing and repaired teeth. Record tooth positions, fillings, extractions and any appliance, distinguishing loss during life from loss after death. Compare these features with actual medical or dental records and reliable descriptions. A family's report of a healed broken leg can guide the comparison, but it does not predict which leg or what deformity must be present.
Record agreement and contradiction. Approximate age, sex and height can narrow a search but fit many people; a well-documented distinctive lesion or dental pattern can provide much stronger evidence. A mismatch must be evaluated for record error, estimate uncertainty or exclusion, not silently ignored. Do not claim that nineteenth-century racial categories or a facial reconstruction uniquely determine identity. Soft-tissue features such as eye colour, hair and skin markings cannot simply be read off a bare human skeleton.
The modern extension is a specialist comparison of ante-mortem records with post-mortem observations, potentially supplemented by DNA profiling from suitable material. This is later corroboration, not a technique available in 1866. The institutional identification guidance emphasizes reconciliation of the two records and the importance of dental or genetic evidence for conclusive identification.[ref]

The chief historical varieties are subglenoid, subcoracoid, subclavicular and posterior shoulder dislocation; treatment restores the humeral head gently, checks the axillary nerve and circulation, and restores useful movement.
The glenohumeral joint combines a large humeral head with a shallow glenoid cavity. Its range of movement depends on the comparatively loose joint capsule; the glenoid labrum, rotator cuff and surrounding muscles provide stability. An injury can therefore lever the humeral head out of the glenoid cavity while tearing the joint capsule and sometimes the glenoid labrum or adjacent bone.
- In subglenoid shoulder dislocation, the humeral head lies below the glenoid cavity, toward the axilla. Old descriptions of displacement “downwards into the axilla” need not mean the persistently overhead arm position now called luxatio erecta.
- In subcoracoid shoulder dislocation, the humeral head lies in front of the glenoid cavity, beneath the coracoid process. This is the familiar anteroinferior pattern.
- In subclavicular shoulder dislocation, the humeral head has passed farther forwards and medially, beneath the clavicle; this is a rarer, more extensive anterior displacement.
- In posterior shoulder dislocation, historically also called subspinous displacement, the humeral head lies behind the glenoid cavity, toward the scapular spine. Modern assessment is particularly alert to this pattern after a seizure or electrical injury. True inferior shoulder dislocation, luxatio erecta, and exceptional superior displacement complete the directional classification; they should not be forced into the common anterior pattern.[ref]Shoulder Dislocations: Emergency Department by the Royal Children's Hospital Melbourne.

An 1867 answer would stress early recognition, relaxation of the muscles, and controlled traction with suitable countertraction or gentle leverage to guide the humeral head through the torn joint capsule. Anaesthesia made relaxation practicable. These are principles, not a reason to reproduce old forceful manoeuvres or indiscriminate pulley traction: force can produce a fracture or damage the axillary artery and brachial plexus.
Current assessment establishes the direction and associated fracture, usually with radiography in appropriate views. Before and after joint reduction, record pulse, perfusion, distal movement and sensation, including sensation over the lateral deltoid muscle supplied by the axillary nerve. A nerve injury accompanying joint dislocation makes prompt restoration of alignment especially important.[ref]

Joint reduction is performed by trained clinicians with suitable analgesia and, when needed, sedation or anaesthesia. Repeated forceful attempts are inappropriate; irreducibility or associated complex fracture requires specialist management.[ref]After joint reduction, reassess the axillary nerve and circulation and confirm alignment and relevant fractures with radiography. A temporary sling relieves pain, followed by progressive physiotherapy to restore movement and rotator cuff function. The balance is between recurrent instability and stiffness: prolonged immobilisation is not a universal solution. Recurrent instability, significant structural injury and persistent weakness require further assessment.[ref]
