01
Non-Union
A fracture failing to heal in the expected timeframe. Surgery is typically required: stable fixation with plates and screws, often combined with bone graft to stimulate healing.

Trauma & conditions
Trauma surgery, plus a complete condition index.
Complex orthopaedic trauma management at Middlemore Hospital — fracture care, non-union, mal-union, painful metalware, and proximal hamstring tear repair. Plus every condition covered across hip and knee.
01 · Trauma
Orthopaedic trauma at Middlemore.
Orthopaedic trauma includes broken bones. Many fractures are managed conservatively; more serious injuries are managed in the public hospital. Healing times range from six weeks to many months. Mr Gormack provides ongoing management of non-union and post-traumatic arthritis.
02
Mal-Union
Bones healing in the wrong position or shape. Surgical correction is considered if there is functional loss or significant deformity.
03
Painful Metalware
Implants that irritate soft tissue once the bone has healed can be removed once the fracture is stable enough to no longer need them.
Featured procedure
Soft-tissue trauma
Proximal Hamstring Tear Repair
A proximal hamstring tear occurs when all three hamstring tendons detach from their pelvic attachment. The patient typically experiences severe buttock pain and difficulty walking. MRI confirms the diagnosis.
Surgical vs non-surgical
Non-surgical management restores approximately 50% of pre-injury hamstring strength. Surgical repair restores approximately 90% of pre-injury strength — making surgery the preferred option for active patients.
Operative details
Surgery is performed in the prone position through a 10–15cm incision. The tendons are reattached to the bone using suture anchors. Surgical time: 90 minutes to four hours.
Recovery
Crutches with touch weight-bearing for two weeks, then gradual increase. Full return to activities: 6–12 months.

Knee
Meniscal Tears
Seven tear types. Catching, locking, swelling. Repair preferred where possible.

Knee
Patella Instability
Kneecap dislocating outward. 60–70% heal without surgery first time; recurrent cases may need MPFL reconstruction.
